TONIC-DISPENSING ooMB.

Application filed November 11, 1924. Serial No. 749,234.

To all waom it may concern:

Be it knownthat I, VVILLARD B. EVANS, a citizen of the United States, residing in San Quentin, in the county of Marin and State of California, have invented a new and useful Improvement in-a Tonic Dispensing Comb, of which thefollowing is a specification. I i

My invention relates to improvements in combs for dispensing hair tonic and the like wherein a supply of tonic contained in the handle of the comb is dispensed past registering apertures and grooves and; through passages formed in the teeth of the comb to delivera regulated flow of tonic.

.Theprimary object of my invention is to provldean improved comb for dispensing hair tonic and the like.

Anotherobject is to provide an improved device of the character described provided with improved means for regulating the flow of tonic.

, tainer foruse in barber or beauty shops and the like, or in homes, and which may be dis- .connected from said main supply. container for use when traveling or at po nts remote from the main supply. a

A further object is to provide a device of simple and durable construction which will aiiord an efiicient means for applying hair tonic and other similar preparations.

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specificatlon wherein like characters of reference are used to designate similar parts through out saidspecification and in which,

Fig. 1 is a longitudinal transverse section of my improved tonic dispensing comb.

Fig. 2 is'a broken plan view of the comb. Fig. 3 is a transverse section taken upon the line 33 ofFig. 2 in jthedirection i11di-.

Fig. 6 is a broken enlarged sectional detail taken upon the line 6-6 of Fig. 2 in the direction indicated. t

Fig. 7 is a broken enlarged sectional detail of one end of the valve core. Referring to the drawings the numeral 1 is used to designate'in general a cylindrical body portion of a comb having a'oonical bore 2 extending therethrough and provided with a hollow handle portion 3 communieating with the bore 2 through an opening 4. Aplurality of teeth Gare formed upon the body portion at substantiallyright anat a point remote .gles to the plane of the handle portion 3,

sa1d teeth 6 having dispensing passages 7 formed therethrough in communication with the bore 2.

A dispensing valve core 8 is rotatably mounted within the bore 2, said core being conical in shape and adapted to fit into the bore 2 to afford a neat turning fit. An axial bore 9 is formed through the core 8, the end of said bore 9 at. the large end of the core, being internally threaded to receive a plug 11 closing said end of the bore. The opposite or small end of the core is externally threaded to receive a cap 12 closing the adjacent end of the bore. Flanges 13 and 14 are formed upon the outer-ends of the plug and cap respectively said flanges substant tially conforming tothe ends of the body portion 1 to give a neat and finished appearance'to the device. 1 j

The end of the body portion 1 adjacent the small end of the bore 2 and core -8 is provided with an annular recess 16 adapted to receive a spring 17 normally'slightly compressed between the back of thei recess and the inner end of the cap 12 to exert an outward pressure against said cap whereby the core 8 is held firmly seated within the conical bore 2, for a purpose hereinafter more fully explained. t a v A plurality of apertures 18 are formed in the core 8 said apertures being adapted to communicate between the bore 9 and the tooth passages 7 when the apertures are caused to register with the adjacent ends of said passages.- An opening19 is formed: in the core to register with the opening 4 :when

the apertures 18 register with the passages 7 whereby a passageis formed between the into the handle.

v communicating between the apertures and the adjacent ends of the tooth passages before the apertures 18 are moved into registering relation with the passages 7.

A core actuating member 22 is secured upon the core 8 and arranged to extend outwardly through a slot 23 in the body portion 1 whereby the core may be turned to cause the apertures 18 to register with the cause said apertures to be movedout ofsuch registering position to fully close the tooth tooth passages 7 for dispensing tonic or to passages and the opening 4: to entirely shut off the flow of tonic from the handle.

Athreaded opening 24 is formed in the end of the handle 3, to receive a reduced extension 26 having apassage 27 therethrough, said extension being adapted to receive the end of a flexible hose connection 28 connected to a main source of supply, not shown, in

any convenient manner. The extension 26 is threaded into the handle to permit said extension to be readily removed and a plug 29 substituted therefor WllBI'BbYdlllB comb may be used at a point remote from the main source of tonic supply if desired.

In operation the core is moved by means of the actuating member 22 to cause the apertures 18 toregister with the tooth passages 7, the aperture 19 being caused to register at the same time with the opening 1 Tonic contained within the hollow handle can now flow through the openings 4 and 19 into the bore 90f the core 8 and thencethrough the apertures 18 into the tooth passages 7 through which it is dispensed onto the hair or onto any surface over which the ends of the teeth 6 may be moved. The ends of the teeth 6 are slightly rounded as at 31 whereby the ends of the passages 7 are prevented from resting flatly upon the surface to which the tonic is being applied, thereby facilitating the flow of tonic outwardly from the teeth.

The grooves 21 are provided in order that the flow of tonic may be easily and effective- .ly regulated through a relatively wide range. As the core is moved to bring the apertures into reg stering relation as above explained, the pointed ends of thegrooves are first moved over the ends of the tooth' passages, said grooves thus forming a restricted passage through which limited .quantities of'thetonic may flow to the tooth passages before' the apertures themselves are moved to registering position. The grooves are tapered to a fine point so that when the points first reach the tooth passages a very small amount of tonic may pass through the grooves to the tooth passages. As the core is turned to advance the grooves further over the tooth passages, progressively increasing amounts of tonic may pass through the grooves to the teeth until the apertures 18 are moved to fully register with the tooth passages 7 at which point a maximum flow is obtained. In this manner the quantity of tonic which is dispensed may be readily regulated by varying the degree to which the core is turned.

By connecting the comb handle to a main source of supply through the flexible hose connection 29 the handle may be kept filled at all times. This arrangement is particularly useful in connection with the barber shops, beauty shops and in homes where daily treatments are to be administered. However, when it is desired to use the comb at a point remote from the main supply, the extension 26 may be removed and the opening closed by a plug 29. as above explained. The handle is adapted to contain a sufficient quantity of tonic to administer several treatments and of course'may be refilled through the opening 2% whenever necessary. The combmay thus be used independently of any connection to a source of supply and may be conveniently packed in a grip for use when traveling. i

The conical form of the core 8 permits the same to be held firmly seated within the bore 2 by means of the spring 17 thereby iiisuring against leakage around the sides of the core. The pressure from the spring also serves to hold the core in any desired position, the frictional resistance due to the pressure exerted by said spring being suflicient to hold the core in closing position or in any desired position regulating the 110W of tonic from the tooth.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is. v
